916. Thalictrum Terrae Novae Greene in Ottawa Nat., XXIV (1910), 

 p. 53. — Stems neither stout nor strongly angled or striate, glabrous 

 throughout, copiously leafy and very few-flowered, 2 feet high or more; basal 

 leaves not seen, the several cauline sessile, ample, deep-green above, 

 glaucescent beneath, all except the uppermost glabrous, but these with 

 a trace of scattered hairs beneath; terminal leaflets somewhat round- 

 obovate, l 1 /* to 1V 2 inches long, of nearly equal breadth above the middle, 

 not deeply but very obtusely 3-lobed, the medium lobe in the staminate 

 plant much the largest, itself usually 3-lobed (seldom so in the fertile 

 plant), all lobes broader than long, the leaflet as a whole always obtuse 

 at base unless obliquely cordate; lateral leaflets smaller, narrower in 

 proportion, mostly either 3-lobed or 2-lobed, a few obliquely oval and 

 entire; staminate plants with flowers usually only 5 or 6 in a single 

 terminal cyme; sepals 4. obovate, obtuse, glabrous; stamens about 20; 

 filaments slenderly clavellate, the thickest part not as wide as the short 

 merely oval anthers; fertile plant bearing a small terminal panicle of 

 10 to 14 flowers, these with a few stamens and numerous pistils; fruit 

 not seen. — Vicinity of Balena, Hermitage Bay, Newfoundland, along 

 streams, collected by William Palmer, 7 July, 1903; his no. 1398, as in

917. Thalictrum Labradoricum Greene, 1. c, p. 53. — Stems not tall, 

 stout, hollow, striate-angled, glabrous, or the upper part sparingly hirtel- 

 lous; foliage thin and delicate, that of the lower part of the plant gla- 

 brous on both faces, but the upper leaves glabrous above, sparsely pu°" 

 escent beneath between the veins, not along them: terminal leaflets 

 rarely cuneately, usually subquadrately somewhat obovate, about 1 in cn 

 long, 3 / 4 -inch wide just below the lobes, obtuse or subcordate at base, 

 the 3-lobes neither decidedly obtuse nor very plainly acute, the middle 

 one largest, often itself 3-lobed; flowers few, in one or two simple, 

 corymbs of 3 or 4, or even solitary; the staminate very large, V2- inC 

 in diameter, the stamens in no part capillary, their filaments clavellate 

 almost from the base and little thicker even at summit, their greates
